St. Bernard Parish water supply was suspected because of low chlorine levels
Louisiana officials: Water safe to drink, but keep it out of your nose
Victim, 4, had played on a homemade water slide
A rare brain-eating amoeba that killed a 4-year-old boy in Louisiana may be a result of Hurricane Katrina.
The water is safe to drink, state officials said, but cautioned against getting it in the nose.
Naegleria fowleri is found in hot springs and warm fresh water, most often in the southeastern United States. It enters the body through the nose and travels to the brain.
The parish water supply came under suspicion because its chlorine levels were low. Chlorine kills the amoeba, said Assistant Health Secretary J.T. Lane.
Naegleria fowleri associated with disinfected public drinking water has caused deaths in only one other case in the United States, according to the CDC. The water came from an untreated drinking water system in Arizona; two children died there in 2003.
Parishes along the Gulf Coast began flushing water lines with chlorine last week.
The Mississippi boy contracted amoebic meningoencephalitis and died last month. Tests at the home where he was playing found the Naegleria fowleri amoeba.
Officials said less than 1% of patients survive the deadly brain infection, but an experimental drug from the CDC has shown promise in fighting it. Kali Hardig, a 12-year-old in Arkansas, survived after contracting the amoeba in July, possibly at a Little Rock water park.
Doctors credited Kali’s mom, Traci Hardig, with her survival, saying she brought her daughter to the hospital early and pushed for more tests.
“If you believe that there’s something more wrong with your daughter or your son than a simple virus or stomach flu, stay in there, hang in there,” Hardig told CNN. “Talk to the doctor … and reassure them that this is not a normal illness.”
The first symptoms of primary amoebic meningoencephalitis appear one to seven days after infection, including headache and fever.
“Later symptoms include confusion, lack of attention to people and surroundings, loss of balance, seizures and hallucinations,” the government agency’s website says. “After the start of symptoms, the disease progresses rapidly and usually causes death within one to 12 days.”
Here are some tips from the CDC to help lower the risk of infection:
• Avoid swimming in fresh water when the water temperature is high and the water level is low.
• Hold your nose shut or use nose clips while swimming.
• Avoid stirring up the sediment while wading in shallow, warm freshwater areas.
• If you are irrigating, flushing or rinsing your sinuses (for example, by using a neti pot), use water that has been distilled or sterilized.
